Re: [PATCH 4/6] ftrace syscalls: Allow arch specific syscall symbol matching

Excerpts from Steven Rostedt's message of Thu Feb 03 01:04:44 +1100 2011:

I'll answer your question here.

quoted

+#define arch_syscall_match_sym_name(sym, name) !strcmp(sym + 3, name + 3)

Instead, you could have:

#ifndef ARCH_HAS_SYSCALL_MATCH_SYM_NAME

static inline arch_syscall_match_sym_name(const char *sym, const char *name)
{
    return strcmp(sym + 3, name + 3) != 0;
}


If an arch needs to make its own, then it can simply override it by
creating its own version and defining:

#define ARCH_HAS_SYSCALL_MATCH_SYM_NAME

Just like they do when an arch has its own strcmp.

Ok, I've changed it over. Just doing a quick regression test on ppc64 &
x86 then I'll repost.

Cheers,
